The document discusses the realities of MOOCs based on a MOOC on sustainable supply chains that had 660 participants from 45 countries. It finds that while 56% logged on, only 18% completed the first half of the first module and 14% finished the first module. It also discusses lessons learned: size of class didn't impact participation levels; completing the first module was important for continuing; and those with higher educational backgrounds were more likely to finish. The document raises questions about the business model for MOOCs.
